It also appears that copper analysis chemicals might be easy to find-
ammonium hydroxide is available as household ammonia, (though I don't
know at what concentration), acetic acid and sodium thiosulfate are
common photographic developing chenicals, and potassium iodide is
readily available on the net (as an emergency measure against nuclear
attack to block radioactive iodine). It is also present in some iodine
tinctures used as antiseptic, along with iodine, so I don't know if
that would work.
